Before, during, and after an emergency, officials from the federal, state, and local governments must coordinate their response.

The response to Hurricane Katrina seemed to be a low point in regard to response.  The public has perceived the responses to Harvey and Irma more positively.  How did this happen?

Mark Herrera is on the Dept. of Homeland Security's Sub-sector Council. He trains first responders and emergency managers across the country in focus, performance and control in extreme situations.

He talks with me about how the various local, state and federal agencies are working together to organize the chaos.  Lesson one:  learn from past mistakes.
